MANUAL MODE HELP SCREEN
This screen is used for controlling the chamber
manually on a step by step basis as opposed to AUTO MODE where the controller
will follow a series of set points in sequence. MANUAL MODE only changes
set points when a new one is entered by the user. In addition to the
standard menu at the bottom of the screen, the following buttons are available:
The following buttons are in the upper temperature
section:
Control The: Touching this box will allow
selecting whether the controller uses the PART TEMP thermocouple control
signal, or the AIR TEMP thermocouple (located in the plenum) as the control
signal.
Set Point: Touching this box will give a
numeric pad to enter the temperature set point the chamber will control to.
Product temp: This box will continually display
the current temperature measured by the PART TEMP thermocouple located in the
chamber workspace.
Air temp: This box will continually
display the current temperature measured by the AIR TEMP thermocouple located
in the chamber plenum.
Boost Heat:
Touching this box will give a numeric pad to enter a value for BOOST
HEAT. The value entered represents the
amount (beyond set point). For example,
if the set point is 100 °C and 10 is entered for boost heat, the controller
will control the air temperature to 110 °C until the PRODUCT TEMP reaches 100 °C,
then it will slowly lower the AIR TEMP to 100 °C.
Boost Cool:
Touching this box will give a numeric pad to enter a value for BOOST
COOL. The value entered represents the
amount of allowable, controlled over-shoot for the AIR TEMP (beyond set
point). For example, if the set point is
–40 °C and 10 is entered for BOOST COOL, the controller will control the air
temperature to –50 °C until the PRODUCT TEMP reaches –40 °C, then it will
slowly raise the AIR TEMP to –40 °C.
Run: Touching this box will start the chamber
controlling to the temperature set point that has been entered. If that
chamber was already controlling to a set point in MANUAL MODE, there is no need
to touch this box again. If the chamber is controlling to a set point,
touching this box will turn it OFF and the controller will stop controlling
temperature.
